A few days ago I was turning on my amp for my lesson, when *phut* the fuse blows. Oh well, just got to use a guitar amp for the lesson (ouch! avoid those low notes!). However, when I got a new fuse I put it in and...blew again. I know I've got a circuit problem, but the repair guy at the local guitar store couldn't tell what it was. His reputation isn't great, but now I'm sort of at a loss. If anyone had's the same problem and knows what it is, help would be much appreciated. By the way, it's a Laney RBW200.
